Explanation : Ethernet is the traditional technology for
connecting wired local area networks
(LANs), enabling devices to communicate
with each other via a protocol -- a set of
rules or common network language.
Token ring is a communication protocol
in a local area network (LAN) where all
stations are connected in a ring topology
and pass one or more tokens for channel
acquisition.
Fiber Distributed Data Interface (FDDI) is
a standard for data transmission in a local
